ABSTRACT:
A sterilizing vacuum cleaner includes at least an ultraviolet lamp disposed around a suction nozzle provided in a bottom portion of a hood secured with the cleaner housing, having a reflecting shade mounted on a back side of the ultraviolet lamp for reflecting the ultraviolet rays emitted from the lamp towards the surface to be cleaned and towards the nozzle duct made of transparent sheet and of ultraviolet-ray transmittable material, so that the dusts or pollutants containing bacteria or fungi laden on the air stream sucked by the cleaner will be sterilized by the ultraviolet lamp for hygienic purpose and for a good housekeeping in a hospital or in any other interior of a building.
